You need to show discipline in all aspects of your training regime to get the results you want. That means eating your greens. Im sure thats not very helpful to your situation but its the truth.

Just like weight training you have to start slowly. Eat small amounts of veggies throughout the day, try them boiled, steamed, raw, grilled. Find out what veggies and how they are cooked you hate the least, and go from there. Growing up I never ate fruits or veggies, hated them. But when I got serious with weight training I had no choice but to get serious with my nutrition.
Started with simply eating carrot sticks, and now I enjoy all varieties of vegeta bles.
